Test: Dell XPS 12 9250 4K surfplatta/dator (sammanfattning)

4K på resande fot. Dell vill avancera i hybridsegmentet genom att sätta nya standarder med sin nya 2-i-1 XPS 12 9259. En 4K-panel, 512 GB SSD-lagring och en Core m7 är några av höjdpunkterna. XPS 12 visar sig vara en mångsidig apparat för vardagsbruk, men är inte särskilt uthållig.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
35 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 27 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 92 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 1000 Hz ≤ 20 % brightness setting

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

En version av testet med mer text kan läsas här (på engelska). 

Dell XPS 12 9250 är en tunn 12,5-tums 2-i-1-dator. Intel Core M7 6Y75-processorn har tillräckligt med kraft för rutinuppgifter och en TDP som tillåter passiv kylning. SSD:n imponerar med höga läshastigheteter och säkerställer ett snabbt system. 

12,5-tumsskärmen med 3840x2160 pixlar övertygar med hög kontrast, bra färgåtergivning och bra betraktningsvinklar. Dessutom är den mycket snabb som inmatningsenhet. Tangentbordsdockan går bra ihop med surfplattans utseende och tilltalar med tysta tangenter och en exakt pekplatta.

Trots det finns viss anledning till kritik. Skärmens vinkel kan inte anpassas till sittställning, vilket inte tillåter en ergonomisk arbetsställning vid skrivbordet. Även om vår testenhet var försedd med den starkaste processorn från Intels Core m-serie hänger den inte riktigt med prestandamässigt. Exempelvis är Microsofts Surface Pro 4 med Core m3 ibland mycket snabbare. Vi hade också hoppats på bättre batteritid. 

Oavsett köprekommendation måste man vara medveten om vilka större fördelar och brister enheten har. Vår testkonfiguration är är definitivt ingen bra affär eftersom den inte kan dra nytta av den dyrare processorn. Samtidigt är den en av få enheter som begåvats med en 4K-panel i 12,5-tumsformat. Om det känns viktigt kanske en konfiguration med en enklare CPU vara intressant.
